METAL STRUCTURE.

Specification of Letters Patent.

Patented Apr. 28,1914.

. Application filed June 24, 1910. a Serial No. 568,711.

To all whom it may concern: I

Be it known that I, ELMER A. WILSON, a citizen of the United States, residing at Niles, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Metal Structures; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others 'skilled'in the art to which it appertains to make and use the same.

My invention relates to metal structures similar to metal lathing but adapted for use as the skeleton of plaster partitions.

My objects are to economize in the expense of erecting fire proof partitions and to provide a durable metal skeleton or lathing which is capable of receiving and anchoring plaster on both of its sides.

Other objects will become apparent from the following description.

The invention consists in the features of construction and combinations of parts hereinafter described and specified in the claims.

In the accompanying drawing:. Figure 1 is a perspective View of a piece of sheet metal, constructed in accordance with my invention. Fig.2 is a cross sectionthereof. Fig. 3 is a front elevation of a modified con? struction, and Fig. A is a cross section of the latter.

Referring first to Figs. '1- and 2 of the drawing, 1 designates a piece of sheet metal 2, 3 and 4 the middle and outside slits 0 each group of three therein, and 5 and 6 the loops which are drawn out ohthe opposite surfaces of the structure: Iti will be noted that a large cavity is formed between each adjacent air of loops 5 and 6 which is capable oFrceiving a considerable quantity of plaster and thereby efl'ectivel anchors the plaster coatings on both si es to the metal sheet. These two coatings are in reality connected or cemented together by theportions which' extend into said cavitles so that a partition thus formed is very durable.

. Them'etalsheet is strengthened by corrugations 8 extending between and parallel with the rowsof loo s.

As illustrate in Figs. 3 and 4, each loop may have its sides bent inward toward each other, as at 9, so that at the middleportion thereof, said sides are substantially arallel. The edges of said sides are preferab y made irregular, as at 10, to afford better anchorage for the plaster.

I claim:

1. A structure, of the character described, consisting of a piece of sheet metal having parallel corrugations therein and a row of arched loops extending longitudinally between said corrugations, each row of loops comprising an equal number struck up on each of the opposite faces of the sheet substantially as shown and described and arranged side by side in pairs, the pairs in alternate rows being staggered with respect to those in the other rows.

2. A structure, of the character described, consisting of a piece of sheet metal having parallel corrugations therein and pairs of arched loops struck up on both sides thereof in alinementbetween said corrugations, each of said loops having its sides bent inward tfiovgard each other, all for the purposes speci- 3. A structure, of the character described,

consisting of a piece of sheet metal having parallel corrugations therein and a row of arched loops arrangedbetween' each pair of said corrugations, each rowof loops comprising-spaced apart pairs extending longitudinally of said corrugations and arranged end to end, each pair consisting of one loop struck up on'each ofthe op osite faces of the sheets substantially as own and described, and the pairs in alternate rows being staggered with respect to thosein'the other rows. v a

4. A structure, of the character described, consisting of a sheet of metal formed with a plurality-of parallel corrugations .and provided with a series of parallel slits arrangedin groups of .three between each pair of parallel corrugations, the metal between the middleslit and one-of the outside slits of each group being drawn outward on one side 'of said sheet'and the metalbetween said middle slit and the other-outside slit being drawn outward on the other side of said sheet forming loops projecting from both surfaces of the structure, each of said s having its sides bent inward toward gations, each row of loops comprising spaced apart pairs extending longitudinally of said corrugations and arranged end to end, each pair consisting of one 100 struck up on each of the opposite faces ot the sheets, and the pairs in alternate rows being staggered with respect to those-in the other rows, each of the loops having its sides bent inward toward each other substantially as and for the purpose specified. 10

In testimony whereof, I aflix my signature, in presence of two witnesses.
